  1. Frog not booting at all

    Hi Thanks already for your tips Yes the battery was replaced Ram is well placed Dip switches are ok It's indeed fat frog displayed on second display with 12 fixtures buttons Attaching a screen on vga out stays black so no more info. Starting with F1 key pushed doesn't do anything more. Do you know wich ic is responsible of the POST power on self test ? Do you know if the is a service manual available ? Thanks for helping. Jp
  2. Frog not booting at all

    Hi, I recently bought a zero88 console on ebay (I think FAT frog). The console doesn't boot up disk drive doesn't make any sound all led flashes once at power up only LCD are on with displaying Frog 2005 zero88.support.com Battery CR2032 was completely empty I checked power supply +12v +5v and -12V are present. Red led on mother board STMAIN 2 (EM7000) is on. Voltages are present 2.5V and 3.3V I removed the RAM and connectors to FDD but that doesn't change anything. It seems that bios is defect. The table is in perfect cosmetic shape and I would be very happy to be able to repair it to replace my old Zero88 alcora. Any advice ? Ideas? Is it a common failure on those consoles ? THX JP Belgium
